Hello Ivan,
Thank you for your message.
You can simply use the
Address Book Manager and specify the path to your address book XML file as described
here. Viewer for Windows and Viewer for Mac/Linux use the same address book format, so once you have your address book exported from the Windows Viewer you can easily import it to the Mac Viewer.
Here's a
quick guide on how to export your address book in Viewer for Windows.
Hope that helps.
